SEER is an authoritative source of information on cancer incidence and survival in the United States. SEER currently collects and publishes cancer incidence and survival data from population-based cancer registries covering approximately 28 percent of the U.S. population.

End of Decade Corrections

The new intercensal population estimates provide an adjustment of previous population estimates based on the actual 2010 Census results. Since the previous population estimates were extrapolated from the 2000 Census, they were prone to increased error as the time from the actual 2000 Census increased. At the national level, the new estimates are not very different from the previous estimates. However, there are more significant differences at the state and county levels that may result in changes in previously published cancer rates.

Graphs Comparing New Population Estimates to Previous Estimates

To summarize the differences between the new estimates and the previous estimates, we have generated a set of time-series graphs for each of the 50 states, the District of Columbia, and the seven SEER registry areas that consist of a portion of a state. Due to difficulties in estimating net migration between censuses, there tends to be more of a difference in the estimates for the more mobile younger populations. Separate plots for ages less than 50 and ages 50 and over have been provided to show the potential differential impact on age adjusted rates depending on the age-profile of the cancer site.

The graphs show trends over time for area populations from the previous and new population estimates and compares them to the actual count from the 2010 Census. The estimates are for the population on July 1 of each year. The 2010 Census count is for the population on April 1, 2010.

On each graph, the years between 2000 and 2011 are on the x-axis and populations are on the y-axis. In order to better show differences in the data, populations on the y-axis do not begin at zero. There are four data sources on each graph: the previous vintage 2009 population estimates for 2000-2009, the new corrected intercensal year population estimates for 2000-2009, the new vintage 2011 population estimates for 2010-2011, and the actual count from the 2010 Census.
